DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a block diagram illustrating a configuration of a safe driving system according to an embodiment of the present invention.

As shown in FIG. 1, the safety operation system according to one embodiment includes a collision detection sensor 100, a black box device 110, a collision state processing unit 120, and a communication unit 170.

The collision detection sensor 100 is installed inside the vehicle and detects an impact applied from outside the vehicle. In one embodiment, the collision detection sensor 100 may be implemented with sensor materials arranged at regular intervals.

The black box device 110 stores the camera 112 and the image storage unit 114. The camera 112 may be a small, lightweight camera module that is mounted on a conventional black box device 110. The image storage unit 114 is implemented as a memory module. In one embodiment, the image storage unit 114 may store a predetermined amount of data, sequentially delete images stored first when the images are input, and store the newly input images.

The collision state processing unit 120 may be implemented as a module for functionally and structurally combining software for driving hardware and hardware for performing the technical mapping. For example, the module may mean a logical unit of a predetermined code and a hardware resource for executing a predetermined code, and may be a code physically connected to the module, or a type of hardware. But can be easily deduced to the average expert in the field of the invention.

The collision state processing unit 120 rotates the camera 112 of the black box device 110 in the direction in which the impact is detected by the collision detection sensor 100 when the collision detection sensor 100 detects an impact. Then, the image is photographed by the camera 112 for a predetermined time and stored in the image storage unit 114.

For example, the collision state processing unit 120 receives the output values from the plurality of collision detection sensors 100. The collision situation processing unit 120 can determine the collision direction because only the collision detection sensor 100 mounted on the collision site among the plurality of collision detection sensors 100 mounted at various positions of the vehicle outputs an electrical signal.

The collision processing unit 120 transmits at least one of the collision occurrence notification message, the photographing completion message, and the photographed image data to the portable terminal of the vehicle owner.

For example, if the collision state notification unit 120 transmits a collision notification message or a photographing completion message to the portable terminal of the vehicle owner, the vehicle owner can confirm the image stored in the black box device 110 mounted on the vehicle, Accident situation can be grasped accurately.

As another example, when the crash condition processing unit 120 transmits the photographed image data, it is possible for the vehicle owner to quickly check the accident occurrence image and the accident image of the vehicle at a remote place.

The communication unit 170 communicates with the portable terminal of the vehicle owner through a communication network. The collision state processing unit 120 transmits at least one of the collision occurrence notification message, the photographing completion message, and the photographed image data to the portable terminal of the vehicle owner through the communication unit 170.

The safe driving system according to another aspect of the present invention further includes at least one CCTV camera 130-1, 130-2.

At least one CCTV camera 130-1 and 130-2 is provided inside the vehicle, and the camera mounted on the black box device 110 can minimize the blindness of photographing It is preferable to install it in such a manner that it can be used.

That is, by further installing the CCTV cameras 130-1 and 130-2 inside the vehicle, it is possible to more accurately grasp the situation around the vehicle when a collision occurs.

According to a further aspect of the present invention, the safe driving system according to an embodiment further includes a drinking meter 140, and a drunk driving preventing unit 150. [

The alcohol measurement device 140 is disposed on the front surface so that the driver can easily measure the seat when seated in the driver's seat. The alcohol meter 140 measures the alcohol concentration included in the driver's exhalation. In one embodiment, the breathalyzer 140 includes a near field wireless communication module such as Bluetooth, infrared communication, or ZigBee, and transmits the measured value to the drunk driving prevention unit 150, which will be described later.

The drunk driving prevention unit 150 receives the measured blood alcohol concentration measured by the alcohol meter 140 through the near field wireless communication. In one embodiment, the near field wireless communication may be implemented in one of the wireless communication technologies such as Bluetooth, infrared communication, and ZigBee.

When the start command is inputted to the vehicle at the set time, the drunk driving preventing unit 150 receives a measurement value of the driver's blood alcohol concentration from the alcohol meter 140 before the vehicle engine starts. And if the measured value is not inputted from the alcohol meter 140 at the set time, the engine start is blocked.

In this case, the set time may be, for example, a time period during which the drunk driving is likely to occur, such as from 10 PM to 6 AM.

The drunk driving preventing unit 150 allows the vehicle engine to start only when the alcohol concentration of the driver measured by the alcohol meter 140 is less than 0.05%.

On the other hand, if the driver's blood alcohol concentration measured by the alcohol meter 140 is 0.05% or more, the drunk driving prevention unit 150 may prevent the engine from starting, restrict the excel function of the vehicle, limit the brake function, The illumination of the inside or outside of the vehicle is turned off, the side mirror is held in a folded state so as not to be stretched, the emergency light is operated, or the acceleration is restricted above the reference speed.

In this way, when the alcohol concentration of the driver is higher than the reference value, it is possible to block the drunk driving by preventing the engine starting of the vehicle or preventing the specific function from being operated. That is, it is possible to prevent an accident caused by drunk driving in advance.

In addition, according to another aspect of the present invention, the safe driving system according to an embodiment further includes a message processing unit (160).

The message processor 160 converts a text message into a voice message and outputs the voice message to a speaker or a vehicle speaker of the driver's portable terminal when the text message is received by the driver's portable terminal during vehicle operation.

The message processing unit 160 may perform short-range wireless communication with the portable terminal of the vehicle driver. And is configured to perform an operation when it is detected in a short distance such that the set portable terminal exists inside the vehicle. And monitors whether or not a message is received by the set mobile terminal while the vehicle is in operation so that the received message is audibly output.

At this time, the message processor 160 may include a technical configuration for receiving a character-type message from the portable terminal and converting the message into a voice-like message.

The message processing unit 160 receives a character-type received message from the portable terminal, converts the received message into a voice-like message, and outputs the converted voice-like message through a speaker provided in the vehicle. Alternatively, the voice-converted voice message may be transmitted to the portable terminal and output to the speaker of the portable terminal.

However, the message processing unit 160 may be a technical configuration in which, when the vehicle is in operation, only a processing command signal is transmitted to convert a character-type message received by the portable terminal itself into a voice-like message and output the message.

And receives the message converted into the voice form from the portable terminal and outputs the message to the speaker of the vehicle. At this time, the message processing unit 160 can recognize that the vehicle is in operation by determining whether the vehicle engine is driven.

Further, the message processing unit 160 may be configured to be installed inside the portable terminal of the vehicle owner. At this time, it may be implemented through a specific application installed in the portable terminal and driven.

The message processing unit 160 can recognize that a specific function such as navigation is performed in the portable terminal, or that the vehicle is traveling when the moving speed of the portable terminal is higher than a certain level according to the position received by the GPS.

If it is determined that the vehicle is in operation, a message of the received character format is converted into a voice form and outputted through the speaker of the portable terminal or through the speaker of the vehicle.

According to a further aspect of the present invention, the message processor 160 converts the received reply message into a text message and returns the message to the sender of the received message.

That is, the message processor 160 receives the reply message for the received message in the form of a voice, converts the received message into a character form, and transmits the converted message. For example, after a text message is received, a voice called "reply " may be recognized, or may be implemented to perform a reply message composing function by inputting a specific vocabulary called "

Accordingly, it is possible to prevent the driver from staring at the portable terminal to confirm or reply to the message during driving. That is, by concentrating more on driving, it is possible to prevent a traffic accident caused by the use of the portable terminal.

2, the black box rotation driving unit 200 fixes the black box device 110 to the vehicle. At this time, the black box rotation driving unit 200 fixes the black box device and drives the black box device 110 so as to be rotatable by 360 degrees.

The black box rotation driving unit 200 may be implemented as a rotation motor capable of adjusting the angle in one embodiment. However, the present invention is not limited to this, and is interpreted to encompass a technical configuration in which the camera 112 is capable of turning the camera in a specific direction so as to be rotatable in the direction in which the collision situation processing unit 120 detects the collision.

3 is an exemplary view showing a camera rotation driving unit according to an embodiment of the present invention.

3, the camera rotation driving unit 210 causes the camera 112 to be fixed to the black box device 110, and drives the camera 112 to rotate at 360 degrees.

The camera rotation driving unit 210 may be implemented as a rotation motor capable of adjusting the angle. However, the present invention is not limited to this, and is interpreted to encompass a technical configuration in which the camera 112 is capable of rotating the camera so as to be rotatable in a specific direction so as to face the direction in which the collision situation processing unit 120 detects the collision.

Hereinafter, a safe operation method according to an embodiment will be described with reference to FIGS. 4 to 6 are flowcharts illustrating a safe driving method implemented in a safe driving system according to an embodiment.

4 is a flowchart illustrating a collision detection method according to an exemplary embodiment of the present invention.

The collision detection sensor senses an impact applied to the outside of the vehicle (S400). When the impact is detected by the collision detection sensor, the collision processing unit rotates the camera in the direction in which the impact is sensed (S410).

In this case, the black box rotation driving unit rotates the camera so that the camera mounted on the black box device rotates 360 ° so that the black box device can be rotated while photographing the black box device in the vehicle.

In another embodiment, while the camera is fixed to the black box device, a camera rotation driver rotates the camera so that the camera rotates 360 degrees.

According to a further aspect of the present invention, when an impact outside the vehicle is detected by the collision detection sensor, the collision situation processing unit may drive at least one CCTV camera capable of photographing the direction in which the impact is sensed, thereby capturing an image for a predetermined time.

 Then, an image is captured in a direction in which the impact is detected by the camera mounted on the black box device or the CCTV camera for a predetermined time (S420).

Even if the camera mounted on the black box device rotates 360 degrees, there is a blind spot which can not be photographed by the camera of the black box device mounted on the ceiling of the vehicle. By installing a CCTV camera, it is possible to minimize such a shooting blind spot and it is possible to grasp the accident situation more accurately.

Thereafter, the collision state processing unit transmits at least one of the collision occurrence notification message, the photographing completion message, and the photographed image data to the portable terminal of the vehicle owner (S430). By informing that an impact is detected outside the vehicle or by performing a message informing that the image capturing due to the impact detection has been performed, the vehicle owner can grasp his / her vehicle condition at a remote location.

It is possible to quickly return to the vehicle and confirm the photographed image stored in the black box device or receive photographed image data through the portable terminal.

In addition, when the collision state sensor detects an impact in the collision detection sensor, the emergency light of the vehicle is turned on or an alarm signal is generated by the ignition key of the vehicle. This allows the owner of the vehicle to immediately notice that an impact has been detected in his vehicle at a remote location.

5 is a flowchart illustrating a method for preventing drunk driving according to an embodiment of the present invention.

When the vehicle engine is started at the set time (S500), the drunk driving prevention unit essentially receives the driver's blood alcohol concentration measurement value through the alcohol meter before the start of the vehicle (S510).

The set time may be, for example, a time period during which a drunk driving is likely to occur, such as from 10:00 pm to 6:00 am.

If the driver's blood alcohol concentration measurement value is input (S520), the input measurement value is compared with the reference value (S530). At this time, if the blood alcohol concentration measurement value is not inputted, the start is blocked (S525). That is, it is essential to perform the drinking measurement in order to operate the vehicle at a time when the possibility of drunk driving is high.

The DUI prevents the vehicle from being started only when the measured alcohol concentration of the driver is less than the reference value. For example, the vehicle engine may be started only when the measured value of the blood alcohol concentration of the driver is less than 0.05% (S540).

On the other hand, if the blood alcohol concentration measured value is 0.05% or more, the DRAW block the start of the vehicle engine or restrict the specific function of the vehicle (S550).

If the measured blood alcohol concentration is higher than the reference value, for example, the alcohol-intoxication prevention unit may restrict the function of the Excel, limit the function of the brake, light the inside or outside of the vehicle, or keep the side mirror in a folded state Or to operate an emergency light, or to limit acceleration beyond the reference speed.

In order to operate the vehicle in a time zone in which the driver is likely to have a drunk driving possibility as in the nighttime, it is necessary to perform the drunk driving measurement and to start the drunk driving only when the measured driver's blood alcohol concentration measurement value is less than the reference value .

6 is a flowchart illustrating a message processing method according to an embodiment of the present invention.

In operation S600, the message processing unit converts the received text message into a voice form and outputs the text message to a speaker or a vehicle speaker of the driver portable terminal in operation S610.

The message processor receives a character-type received message from the portable terminal, converts the received message into a voice-like message, and outputs the converted voice-like message through a speaker provided in the vehicle. Alternatively, the voice-converted voice message may be transmitted to the portable terminal and output to the speaker of the portable terminal.

Preferably, however, the message processing unit may transmit only a processing command signal to convert a character-type message received by the portable terminal itself into a voice-type message and output the message when the vehicle is in operation.

And receives the message converted into the voice form from the portable terminal and outputs the message to the speaker of the vehicle. At this time, the message processor can determine that the vehicle is in operation by determining whether the vehicle engine is running.

Further, the message processing unit may be implemented in a specific application installed in the mobile terminal and driven by the mobile terminal.

The message processing unit recognizes that the vehicle is traveling when the specific function such as navigation is performed in the portable terminal or the moving speed of the portable terminal is higher than a certain level according to the position received by the GPS.

If it is determined that the vehicle is in operation, a message of the received character format is converted into a voice form and outputted through the speaker of the portable terminal or through the speaker of the vehicle.

Thereafter, the message processing unit converts the received message into a text message and returns it to the sender of the received message (S640) when the reply message for the received message is input by voice (S620, S630).

The message processor receives the reply message for the received message in the form of a voice, converts the received message into a character form, and transmits the character string. For example, after a text message is received, a voice called "reply " may be recognized, or may be implemented to perform a reply message composing function by inputting a specific vocabulary called "

Accordingly, it is possible to prevent the driver from staring at the portable terminal to confirm or reply to the message during driving. That is, by concentrating more on driving, it is possible to prevent a traffic accident caused by the use of the portable terminal.
